EPC or ePC (Glossary of Printed Electronic terms)
Electronic Product Code. 'A numbering scheme that can provide unique identification for physical objects, assemblies and systems. Information is not stored directly within the code - rather, the code serves as a reference for networked (or Internet-based) information, in other words, the code is an "address" - it tells the computer where it should go to find information on the Internet.
The EPC requires relatively few parameters to determine the design:
Number of bits - i.e. How much information is needed to provide a unique identity in every single product manufactured, sold and consumed in the global supply chain?
Bit "partitions" - i.e. What is the best way to organise - or "break up" - the numbers/figures so that we achieve as many unique combinations as possible, while also expediting Internet searches? Consider this an exercise in determining the best "search hierarchy" - like a postal address - which goes from country to city, to zip code, to street, to house and individual
As the detail or level of the hierarchy increase, the speed and accuracy of the search will likewise increase, but the possible combinations of unique numbers will decrease.
